This interactive scatter plot visualizes the Iris dataset, comparing sepal length against sepal width across three species. The visualization uses d3.csv to load data and d3.scaleLinear, d3.scaleOrdinal, and d3.axisBottom/axisLeft to render the chart. Users can hover over the legend to highlight individual species while fading others. The chart displays a title, subtitle, source attribution, and uses the BBC color theme to differentiate data points.
